Super can have several meanings at the same time. When I use that word, super is not super at all sometimes. It can be also for something normal or well expected. Super can replace bad words also. Super is used when you don’t want to speak with somebody. Super is the material that Superman is made of. Super (in Dominican Republic) is a Supermarket.
From an expression of the face you can see if Super is realy Super or something else is.
